I have been using the services of Duel Products in Wylie, TX for more than ten years. They have always produced excellent machine work at very reasonable prices. If a problem is found, which is quite rare, they are quick to fix the issue and suggest changes to make the product cheaper and easier to manufacture. When I next need something machined, coated, and/or screen printed, I will not hesitate to contact them again. Their work is good and they are pleasant to deal with on the phone or face to face.
